Over-Voltage Protection battery charger over-voltage protection event defined condition where voltage exceeds over-voltage protection threshold (VOVP) (4.4V). this over-voltage condition occurs, charger control circuitry will shut down device. charger will resume normal charging operation after over-voltage condition removed. Over-Temperature Protection battery charger thermal protection circuit which will shut down charging functions when internal temperature exceeds preset thermal limit threshold (145°C). Once internal temperature falls below thermal limit, normal charging operation will resume. Short-Circuit Protection AAT2557's contains internal short-circuit protection circuit that will trigger when output load current exceeds internal threshold limit. Under short-circuit conditions, output regulator will current limited until short-circuit condition removed from output until package power dissipation exceeds device thermal limit.

When battery connected pin, charger checks condition battery determines which charging mode apply. battery voltage below VMIN, charger begins battery pre-conditioning charging programmed constant current; e.g., programmed current 150mA, then pre-conditioning current (trickle charge) 15mA. Pre-conditioning purely safety precaution deeply discharged cell will also reduce power dissipation internal series pass MOSFET when input-output voltage differential highest. Pre-conditioning continues until battery voltage reaches VMIN (see Figure this point, charger begins constant-current charging. current level this mode programmed using single resistor from ISET ground. Programmed current from minimum 15mA maximum 500mA. Constant current charging will continue until battery voltage reaches voltage regulation point, VBAT. When battery voltage reaches VBAT, battery charger begins constant voltage mode. regulation voltage factory programmed nominal 4.2V (±0.5%) will continue charging until charging current reduced programmed current. After charge cycle complete, pass device turns device automatically goes into power-saving sleep mode. During this time, series pass device will block current both directions, preventing battery from discharging through battery charger will remain sleep mode, even charger source disconnected, until following events occurs: battery terminal voltage drops below VRCH threshold; charger recycled; charging source reconnected. cases, charger will monitor parameters resume charging most appropriate mode.
